Injen X-1059 Replacement Air Filter – SP1122 / SP1129 Intakes (BMW N20 / B58)

OVERVIEW

The Injen X-1059 is the replacement air filter for the Injen SP1122 and SP1129 intakes. Fit it at service time to restore the airflow and filtration of the original element.

The X-1059-BB uses Injen's SuperNano-Web dry synthetic media — no oil and no risk of oil migrating onto a hot-film MAF sensor. Wash it in warm water, let it dry and refit it.
